We advise doubling the wattage of the amp with the speaker. For your amp that would be around 1100W. A 600W speaker technically has enough power for the amp, it is much more likely to be damaged when playing at higher volumes. Subsequently, the Ohm rating of the speaker is 8 Ohms while the amp's rated at 4 Ohms. It is safe to install an 8 Ohm speaker your amp as you can safely go over in Ohm ratings, just not under.
